The Marsh Vehicle Detector and 4-foot-by-12-foot Preformed Saw-Cut Loop Kit are designed for vehicle detection installations whose paving has already been poured. The package comes with 100 feet of #16 AWG cable.
The Vehicle Detector is an intelligent, extremely flexible product. It is designed to intelligently adjust to environmental conditions, virtually eliminating false detection.
The Preformed Saw-Cut Loop Kit consists of multiple turns of wire, bundled together to form a 4-foot-by-12-foot easy-to-install loop. Also included are two tubes of polyurethane loop sealant to close up the channel cut in the pavement for the loop.
A concrete saw is used to cut a rectangular pattern in the concrete or asphalt. The one-piece loop is set into the channel, and the sealant is applied with a caulk gun.
The standard lead-in length is 20 feet; if you want a longer lead-in, use the drop-down menu to specify the length you desire.
If your paving hasn't been installed yet, the Marsh Direct Burial Loop and Marsh Vehicle Detector is a better choice.
